Miami Dolphins training camp preview: 20 most pressing questions

Taimy Alvarez / Sun Sentinel

Matt Moore has served as Ryan Tannehill’s backup for the past three seasons, but the Dolphins added veteran quarterback Josh Freeman to the training camp roster this summer, and the former Tampa Bay starter seems to be pushing Moore for his spot. Freeman, who struggles with consistency, has started 60 games in his NFL career, but Moore’s the only backup quarterback in the AFC East that has a winning record as a starter. Problem is Moore’s practice habits need to improve.

Louis Delmas (pictured) and Will Davis participated in Miami’s minicamp sessions this summer, and should be cleared to practice with their teammates despite being eight months into rehabbing their surgically repaired right knees. The biggest concern the Dolphins should have about Delmas, the team’s starting free safety, and Davis, a contender for the starting cornerback spot, is whether or not they are pushing too fast, too soon?

The Dolphins yet again spent more money to upgrade the roster than any other team in the NFL. But will owner Steve Ross get a return on his investment? Here is a look at the Sun-Sentinel’s 20 things that could determine success or failure.
